Please ask your pulley, belt andcoupling supplier, or send an inquiry to our own technical department.IMPORTANT NOTICE. Cylindrical roller bearings (NU) must always be subjected to at least 25% of theirmaximal radial load for correct motor behavior. In many cases the weight of the element supported by the bearing, includingthe external forces, is greater than the minimum required loading.RETAINERSEG series uses radial-shaft spring-loaded retainers with double lip in order to improve motor obturation efficiency.MotorFrame 824-6-82-4-6-824-6-824-6-8RetainerD-end x1295x120x12Note: The dimensions of the bearings and the retainers are not binding to the series.

ELECTRICALFEATURESPROTECTION SYSTEMSOn request, the following motor protection systems can be supplied: PTC temperature probes, thermistors inserted in the winding. Bimetallic temperature probes, usually NC encased, or usually NO open. Pt100 temperature probes in the bearings. Heating resistors in the winding.ASYNCHRONOUS MOTORS TO BE USEDWITH A FREQUENCY CONVERTEREvery CEMER motor can be powered by a frequency converter, but always according to the following technical requirements:If the customer does not take any precaution on the design of the electrical system, motors with regular insulation grademay fail and break down. Voltage peaks on the motor terminals may be of a very high amplitude and considerable length intime. Depending on the type, length and configuration of the motor winding, impulses can increase the voltage of the linkconverter by up to two times.11If the link voltage of the converter does not exceed 600V, CEMER motors can operate in conjunction with a convertersupplied with a voltage of up to 420 V without the need of a rear filter. A star (Y) connection should be ordered for thosemotors.From casings 280 and upwards, COSGRA recommends the use of an insulated bearing on side B (fan side) in order to avoidcurrents that can affect them.Advice notices for the correct behavior operationof motors with a converter.Motors are only a complex part of an electrically-actuated system. Modern motors and converters offer protection againstthermal overload. However, they are not protected against excess voltage peaks on the motor terminals. Because of theactuation system, problems can be exacerbated in the absence of filters on the converter outlet, and/or excessive cablinglength. This often causes serious damage to the insulation of the motor.Several options exist to optimize the electrical actuation system:.- Filter circuits on the converter outlet (obturation, du/dt, sine).- Motors with reinforced insulation systems.- A combination of both of the above.The person responsible for the specification must carefully select the various components of the system. It is their responsibilityto ensure that the terminal voltage does not exceed permitted levels. This also includes selecting the motor insulation, alwaysbearing in mind the effects of other components in the system.Our technical department is highly specialized in these type of applications and are able to advise you on the correctselection of motor for each application.sacosgra
